Abstract
A drive assistance device for a backhoe loader vehicle has an elongated bar member having a hook or post component at its lower end which is configured to be placed around or adjacent to the directional control pedal of a hydrostatically controlled backhoe loader vehicle. The elongated bar member has a handle at its upper end to allow the vehicle operator to grasp the bar member. When the lower end of the bar member is connected to the pedal, the bar member extends up to the operator, who can then easily and safely control the movement of the pedal, allowing it to be placed in neutral to maintain the vehicle in a stationary position while digging is being done, and to be moved ahead, while safely operating the steering wheel, to move the vehicle in the appropriate forward direction.
Description
- This invention relates to a device which allows the operator of a hydrostatically controlled backhoe loader type vehicle to easily and safely control the vehicle during backhoe digging operations.
- Backhoe loader vehicles are important and functionally necessary pieces of machinery which are utilized for a variety of purposes. One of the most common uses for such vehicles is for scooping out holes, trenches, and similar digging operations. Yet it is critical that these vehicles be readily moveable during such operations. For example, when digging elongated trenches, the backhoe loader vehicle must be constantly moved in a forward direction, to allow the vehicle to scoop out dirt along the full length of the trench behind the vehicle. Unfortunately, the need to operate a backhoe loader for digging, for moving the vehicle forward, and for then repeating this process over and over again, presents a number of important safety issues.
- Trench digging operations require the operator of a backhoe loader to be positioned on the vehicle's seat such that he faces backward while using the backhoe component for digging. When it is necessary to move the vehicle slightly forward to dig out the next section of the trench, the operator must turn and face forward in the direction of travel. In older to do this safely, the operator must leave the cab of the vehicle, rotate the vehicle's seat 180°, climb back into the vehicle, and then move the vehicle the appropriate distance forward. The operator must then again leave the vehicle, rotate the seat back so that it is rearward facing, re-enter the vehicle, and continue with the backhoe digging operations. The steps of this procedure must be repeated numerous times while the trench, sometimes quite long, is being dug.
- As a practical matter, operators of backhoe loaders in the field seldom, if ever, take the time to repeatedly leave their vehicles and reposition the seating so that they are at all times safely facing the direction in which they are working or driving. Instead, once a section of a trench is dug, the common practice is for the operator to remain in the rearward facing seat of the vehicle and reach down to the hydrostatically controlled directional pedal on the floor of the vehicle, while attempting to steer in a forward direction. This practice, while routine, is very unsafe. Since the driver/operator is not in the proper position to drive and steer the vehicle ahead, he has limited and restricted maneuverability and lack of control.
- Even if the operator follows the recommended practice of leaving the cab of the vehicle each time he needs to change the seat orientation, there is the enhanced risk that the operator will slip, or otherwise be injured while repeatedly entering and re-entering the vehicle, during the many times the vehicle must be moved.
- It is thus the object of the present invention to provide a driver assistance device for a backhoe loader vehicle having hydrostatic forward and reverse directional pedal controls, which permits the driver to operate the vehicle safely, while at all times remaining seated in the vehicle, with the vehicle's seat facing rearward.
- This object is accomplished by the present invention, a driver assistance device comprising an elongated bar member having a hook or post component at its lower end which is configured to be placed around or adjacent to the directional control pedal of a hydrostatically controlled backhoe loader vehicle. The elongated bar member has a handle at its upper end to allow the vehicle operator to grasp the bar member. When the lower end of the bar member is connected to the pedal, the bar member extends up to the operator, who can then easily and safely control the movement of the pedal, allowing it to be placed in neutral to maintain the vehicle in a stationary position while digging is being done, and to be moved ahead, while safely operating the steering wheel, to move the vehicle in the appropriate forward direction.
- The novel features which are considered as characteristic of the invention are set forth in particular in the appended claims. The invention, itself, however, both as to its design, construction and use, together with additional features and advantages thereof, are best understood upon review of the following detailed description with reference to the accompanying drawings.

Driver assistance device 1 compriseselongated bar member 2 havingupper end 4 andlower end 6.Bar member 2 itself consists ofupper bar element 10 withhandle 11 atupper end 4, andlower bar element 12. The lower end ofbar element 10 hasinternal notch 16 andelongated opening 18. The upper end ofbar element 12 hasupstanding support tab 20 and threadedhole 22. The lower end ofbar element 10 is positioned on the upper end ofbar element 12 such thatsupport tab 20 is located withinnotch 16 and opening 18 is over threadedhole 22. Screwconnection member 24 is inserted into opening 18 and then screwed tightly into threadedhole 22 in order to securebar element 10 tobar element 12. -
Lower end 6 ofbar member 2, the lower end ofbar element 12, comprises hook shapedcomponent 14.Hook component 14 can be secured tobar element 12 via connection toupstanding plate 26 byscrew connection members lower end 6. In bothinstances hook component 14 is configured to substantially circumscribe the pedal of a hydrostatic backhoe loader vehicle which controls forward and reverse movement of the vehicle. SeeFIG. 5 . -
Driver assist device 1 is designed to be used onbackhoe loader vehicle 40 havingbackhoe component 48 attached at the vehicle's back end and loader/shovel component 50 attached at its front end.Vehicle 40 utilizes vehicledirectional control pedal 42 to operate a hydrostatic system. The system provides that whenpedal 42 is pushed down/forward,vehicle 40 moves in aforward direction 60. Whenpedal 42 is pulled up/back,vehicle 40 moves inreverse direction 70.Vehicle 40 remains in neutral whenpedal 42 is in a mid-position.Steering wheel 44 operates to turnvehicle 40, whether it is moving in the forward or reverse direction.Operator seat 46 is designed to rotate in order to face forward whenvehicle 40 is to be moved inforward direction 60 and to face backward when the vehicle is to be moved inreverse direction 70.FIGS. 7 and 8 show vehicle 40 with itsseat 46 facing backward. - In operation, for instance when
backhoe component 48 ofvehicle 40 is used to dig a trench, thevehicle operator 80 is in position inseat 46, facing backwards. When digging is completed on one section of the trench,vehicle 40 must be moved forward, in the proper direction, so that the next section of the trench can be dug. In order to movevehicle 40 forward, safety dictates thatvehicle operator 80 leave the vehicle, rotateseat 46 180°, remount the seat, and, while steering by turningsteering wheel 44, push down onpedal 42 to move the vehicle in the proper direction.Operator 80 then must placepedal 42 in its neutral position, once again leavevehicle 40, rotateseat 46 back to its rear facing position, remount the seat, and continue digging the trench withbackhoe component 48. This process must be repeated until the trench is completely dug out. - As a practical matter, however, operators in the field seldom, if ever, take the time to repeatedly leave their vehicles and reposition seating. Instead, once a section of a trench is dug, the common practice is for the
operator 80 to remain in the rearward facingseat 46, and reach down topedal 42 while attempting to steervehicle 40 in a forward direction. SeeFIG. 8 . This is an unsafe practice, for obvious reasons, e.g. limited and restricted maneuverability, lack of control of directional vehicle movement, etc.Driver assistance device 1 of the present invention provides a safe alternative. - In use, hook shaped
component 14 ofdriver assistance device 1 is positioned aroundpedal 42 ofvehicle 40, so thatbar member 2 extends up towards rear facingseat 46, as seen inFIGS. 5 and 7 .Operator 80 can easily and readily hold ontohandle 11 ofdriver assistance device 1, while remaining seated and facing backwards invehicle 40. Whenvehicle 40 must be moved forward,operator 80 can simply push down on driver assistdevice 1, which forcespedal 42 down, and turn his head or body slightly to easily and safely usesteering wheel 44 to steer the vehicle. SeeFIG. 7 . - When
vehicle 40 is moved forward and properly positioned, bar member is simply pulled up to placepedal 42 into its neutral position andoperator 80 can then once again turn his attention to usingbackhoe component 48 to continue the digging operation. In this manner,operator 80 never has to leaveseat 46, but can still safely conduct digging operations. - While
drive assistance device 1 withhook component 14 can be used on the majority of backhoe loader vehicles, some vehicles utilize a directional control pedal with a configuration which is not conducive to the hook component. The pedals on these vehicles have mid-section openings. For these vehicles, driver assist device 1 a is provided in which barelement 12 is replaced bybar element 112 havingpost component 114 onlower end 116 in lieu ofhook component 14 ofbar element 12. SeeFIGS. 2 and 4 .Bar element 112 is connected to barelement 10 in the same manner in which barelement 12 is connected to barelement 10 to formelongated bar member 2 a; i.e. the upper end ofbar element 112 has anupstanding support tab 120 which is positioned withinnotch 16 ofbar element 10 and threadedhole 122 into whichscrew connection member 24, having been positioned within opening 18, is screwed. -
Post component 114 is configured to be inserted into opening 144 ofpedal 142, as seen inFIG. 6 . Operation of thevehicle having pedal 142 with drive assistance device la is the same as previously described with regard to its use with avehicle having pedal 42. - Certain novel features and components of this invention are disclosed in detail in order to make the invention clear in at least one form thereof. However, it is to be clearly understood that the invention as disclosed is not necessarily limited to the exact form and details as disclosed, since it is apparent that various modifications and changes may be made without departing from the spirit of the invention.
